Supervision method of software effectiveness of in-use coal mine safety monitoring and control system

Key points and methods of basic function supervision of software of in-use coal mine safety monitoring and control system were summrized. A supervision method of software effectiveness of in-use coal mine safety monitoring and control system was proposed by data consistent check, including software real-time performance consistent check, software history data consistent check, software dual computer data consistent check, software and networking system consistent check and mine duty record and monitoring main computer duty record.
